my heads have been milled .060, and i have a TREX shaft, mahle pistons with 4cc valve reliefs (plenty of room, trust me), comp oem replacement lifters...my question is...if i just by 7.350 pushrods, and use stock rocker arms, will this work? will the lifter be able to make up for .010 without hurting anything?

 

All things being equal, you would have .010 more lifter preload, but the base circle of your TREX is probably smaller than your OEM cam so you may actually end up with less than stock lifter preload. That's probably not a good idea.

 

ok. what if i go adjustable rocker arms? should i go with a 7.400 pushrod or a 7.350 pushrod then? this is all very confusing to me.

 

You are going to have to mock up the engine and use a pushrod length checker to be sure. Make sure the roller on the rocker are stays in the middle of the valve stem during the intire 360 degree rotation of the cam.
